concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that react

representation‚ which more clearly displays the relationship‚ view Figure 2. The rate at which the reaction occurred for the 100% concentration is 1.45 mg/dL per minute. For the 50%‚ the rate was 3.05 mg/dL per minute‚ and for the 25%‚ the rate was 2.76 mg/dL per minute. As seen‚ the rate fluctuated from the lowest rate at 100% and the greatest rate occurring at 50%. As mentioned earlier‚ the Collision Theory states the rate of a chemical reaction is proportional to the number of collisions that occur

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

Flat Taxation is Equal Taxation Tax rates in America have been changed and reformed to try and meet the needs of the current economy‚ or to make a politicians look good. Recent questions have been asked about whether we should reform the entire style of tax rates in America. Future generations are going to feel the burden or benefit from tax choices we make now because it takes time for things of this magnitude to take place. Also it is a possibility that the future generation may need new tax

There was a time when one out of a human marriage’s used to end in a divorce. “ A divorce is like and ampulation: you survive it‚ but there’s less of you” by Margaret Atwood. It is a legal action between married people to terminate their marriage relationship. It can also be defined as the dissolution of marriage. In my opinion‚ for almost all people it is very hard to deal with this kind of situation. No one enters a

The Interest Rate Essentially‚ interest is nothing more than the cost someone pays for the use of someone else’s money. The interest rate that applies to investors is the Federal Reserve’s federal funds rate. This is the cost that banks are charged for borrowing money from Federal Reserve banks. Why is this number so important? It is the way the Federal Reserve (the "Fed") attempts to control inflation. Inflation is caused by too much money chasing too few goods (or too much demand for too little
